Ensure the following clearances are maintained when choosing an installation location. B B A D NOTE: The service clearances are recommendations. If you are unable to maintain those specific clearances, it might not be possible to service the boiler without removing it from the space. NOTE: For closet installations, a combustible door or removable panel is acceptable front clearance. A 3" minimum clearance must be provided from the appliance front cover to the removable panel or combustible door. When locating the boiler, it is essential that sufficient space be allotted for the installation and maintenance of components, such as: Flow Switch, Thermostatic Mixing Valve (TMV), Pressure Relief Valve (PRV), Shut-Off and Drain Valves, Expansion Tank, Condensate Drain and Assorted Equipment. 3 Wall Mounting C Figure 3 - Minimum Clearances Dimension Description A Top B Right or Left Side C Front D Bottom Not Displayed Back Table 2 - Minimum Installation and Service Clearances Clearance 14" (355.6 mm) 2" (50.8 mm) 18" (457.2 mm) 12" (304.8 mm) 0" (0 mm) Minimum Clearances from Combustible Materials Hot Water and Exhaust Vent pipes - at least 1" from combustible materials 16 " Figure 2 - Mounting the Bracket on 16" Center Studs MOUNTING TO A WOOD STUDDED WALL 1. Position the upper wall mounting bracket on the wall. Ensure the bracket is level and the drilling holes are on stud. Then use the bracket as a template to mark four (4) drilling holes on the wall - two (2) on each side of the bracket. See Figure 2 for details. 2. Drill and plug the wall. Then secure the upper mounting bracket using the provided (Fischer S 10x50) screws and field provided washers for wood mounting. 3. Install the lower mounting bracket on the boiler. Then hang the boiler on the upper mounting bracket. Ensure the boiler is level. Then use the lower bracket to mark the lower bracket drilling holes. 4. Drill and plug the wall and secure the lower mounting bracket using field provided screws. Then adjust the lower mounting bracket on the boiler. Ensure the boiler is installed plumb. Tighten the bracket to the boiler. EN - Installation Quick Guide 3 STEP 2 Installing 4 Checking the Rating Plate CAUTION The boiler is factory configured to operate on Natural Gas. If conversion to Propane Gas is required, the conversion kit supplied with the boiler must be used. DANGER · Before connecting the gas supply, determine the gas type and pressure for the boiler by referring to the rating plate. Use only the gas type indicated on the rating plate. Using a different gas type will result in abnormal combustion and malfunction of the boiler. Gas supplies should be connected by a licensed professional only. · The boiler and its gas connection must be leak tested before placing the boiler in operation. · The boiler cannot be converted from Natural Gas to Propane or vice versa without the supplied gas conversion kit. DO NOT attempt a field conversion of the boiler without a gas conversion kit. Doing so will result in property damage, serious personal injury, or death. NTI IS NOT LIABLE FOR ANY DAMAGES (PROPERTY DAMAGES, PERSONAL INJURIES, OR DEATHS) RESULTING FROM IMPROPER CONVERSIONS. Federal law prohibits removal of this label before consumer purchase.

Condensation is slightly acidic (typically with a pH of 3 to 5) and must be piped with the correct materials. Never pipe the condensate using metal pipe subject to corrosion. Plastic PVC or CPVC pipe are the only approved materials. A condensate neutralizer, if required by local authorities, can be made up of lime, marble, or phosphate chips that will neutralize the condensate. 2. The boiler is equipped with a barbed outlet fitting. Connect the supplied hose to the fitting and route it with a downward slope away from the boiler to a local drain. If the boiler condensate outlet is lower than the drain, use a condensate removal pump. This pump has two leads to connect an alarm or other warning device to alert the user of an overflow, which could cause property damage. 3. If a long horizontal run is used, create a vent in the horizontal run to prevent a vacuum lock in the condensate line. 4. DO NOT expose the condensate to freezing temperatures. 5. It is very important you support the condensation line to assure proper drainage. EN - Installation Quick Guide 11 STEP 2 Installing 7.9 Gas Connection It is recommended that this boiler be connected as the first appliance downstream of the gas meter to ensure a sufficient gas supply. To connect the gas supply: 1. The gas connection fitting on the boiler when the supplied adapter is installed is ¾" NPT. The pipe size must not be less than ¾". NOTE: DO NOT USE 1/2" quick flex gas lines! Doing so will result in improper appliance operation. 2. The supply line must be sized for the maximum input of the boiler being installed. If there are additional gas appliances on the main supply line, measure the size of the supply line according to the COMBINED total maximum BTU/H draw for the appliances as if they were operating at the same time. 3. Measure the length of the gas supply line from the gas meter to the boiler. The boiler must be installed downstream of the gas meter to ensure adequate gas supply. Use the tables in the installation manual or refer to the gas line manufacturer's sizing information to determine the correct supply pipe size. 4. The National Fuel Gas Code (NFPA 54) requires that a sediment trap (drip leg) be installed in the gas line on boilers not so equipped. The drip leg must be accessible, a minimum of 3" in length, and not subject to freezing conditions. 5. A manual gas shut-off valve should be installed in the gas supply line close to the boiler. See Figure 9. 6. To facilitate any future maintenance, it is also recommended that an approved gas union fitting be installed in the supply line between the shut-off valve and the ¾" NPT connection on the boiler. 7. Use a manometer to test the gas pressure to make sure it meets the minimum standards and does not exceed the maximum standards of the boiler. 8. Leak test the gas line pipe before placing the boiler in operation. Only use approved leak detector liquid solutions to check for leaks. 9. Do not operate the boiler until all connections have been completed and the heat exchanger is filled with water and purged of air.
